The AS4C256M8D2-25BCN is a 2Gb DDR2 SDRAM memory chip organized as 8 banks of 32Mbit x 8. It supports high-speed data transfer rates with a system frequency of up to 400 MHz and features a 4-bit prefetch architecture. The device offers programmable CAS latency options of 3, 4, 5, 6, and 7, as well as programmable additive latency and burst lengths of 4 and 8. This memory chip includes on-die termination (ODT), automatic and controlled precharge commands, and supports power-down mode, auto refresh, and self-refresh capabilities. The refresh interval is 7.8 ¬µs at temperatures from -40¬8C to 85¬8C and 3.9 ¬µs at temperatures from 85¬8C to 105¬8C. The AS4C256M8D2-25BCN operates with a power supply of 1.8V ¬± 0.1V and is available in a 60-ball FBGA package, making it suitable for various applications requiring reliable and efficient memory solutions.
